| 摘 要： | 层间氧化带是矿床形成的直接控制因素,铀矿化位于层间氧化带的尖灭部位,产于相邻氧化带发育的灰色砂体中,层间氧化带是找矿的地球化学标志和矿床形成的直接控制因素。通过对该区地质构造和沉积演化历史的系统分析,重点描述中侏罗统直罗组和下白垩统华池—环河组层间氧化带的特征,进而确定本区具备形成层间氧化带砂岩型铀矿的条件。

| Abstract: | Interlayer oxidation zone is the direct factors of the mineralization.The Uranium mineralization is located at the pinch position of interlayer oxidation zone and occurred in the gray sand body among adjacent oxidation zones.Interlayer oxidation zone is the geochemical prospecting indicator.By the systematic analysis of the geologic structure and evolution,this paper focuses on studying characteristics of interlayer oxidation zone of the Zhiluo Formation of Middle Jurassic and Huachi-Huanhe Formation of Lower Creteceous,and thus it is determined that this area possesses the condition of the formation of interlayer oxidation zone sandstone-type uranium ore. |
